Sir Paul McCartney: 'Music Helps Me Revisit Late Beatles'

Sir Paul McCartney says his music enables him to maintain contact with his late wife Linda and former members of The Beatles.

The singer told a press conference in London that his concerts were his way of ”revisiting” John Lennon and George Harrison.

"I'm sort of thinking about George ... similarly with John and Linda. In a way you're kind of in contact with them again you know," he said.

Sir Paul admitted the experience often left him “sad” and “emotional”.

He was speaking to journalists ahead of the release of his new concert CD and DVD, 'Good Evening New York City'.

Released on December 7, the package features highlights from Sir Paul's three-night residency at New York's Citi Field in July.

The album also coincides with the former Beatles' seven-date European tour in December, which concludes in London on December 22.
